魔杖 solarize() 函数- Python

魔杖solarize()函数是Python中PIL(Python Image Library)库中一个预定义的函数。使用该函数可以快速将在RGB颜色空间中的像素进行倒置(solarize)处理。solarize()函数详细信息如下：

def solarize(image, threshold=128):
    """
    Invert all pixels above a threshold 
    
    Args:
    image: A Python Imaging Library (PIL) image object.
    threshold: A number that represents the cutoff point in a range of 0-255
    
    Returns:
    A PIL image object.
    """

如此看来，solarize()函数可与任何返回图像对象的函数一起使用。使用时，可以指定threshold值以控制solarize的效果。

示例代码:

from PIL import Image
from PIL.ImageOps import solarize
# Open the image file
filename = "example.jpg"
with Image.open(filename) as image:
    # perform Solarization
    solarized_image = solarize(image, threshold=64)
    # show the original and the new image
    image.show()
    solarized_image.show()

```python
from PIL import Image
from PIL.ImageOps import solarize
# Open the image file
filename = "example.jpg"
with Image.open(filename) as image:
    # perform Solarization
    solarized_image = solarize(image, threshold=64)
    # show the original and the new image
    image.show()
    solarized_image.show()
